If one joint failed, the rest may be ready.

Also, the replacement teeth are guaranteed to be differently -
shaped than the worn teeth, making sharpening a much more
time-consuming process than it needs to be.


I suppose size/weight could have some implications here, too. Put a
single different sized tooth on and throw the blade out of dynamic
balance.


I wouldn't be too concerned there.

On my dry saw, I've discovered that I'd been cutting steel using
a blade missing a couple teeth. Performance was down.
but it still worked without discernible vibration.


Doesn't your dry saw run at a considerably slower RPM?


My nit is that they never showed any additional silver solder being
applied. Is there enough after removing the teeth? I'd be wary of
that.

He *implies* that he put fresh silver solder in the joint
between shots. (Must look up silver solder *paste*!)


Powdered silver solder in white flux, just what we need.


Substitute black flux and you've got a deal!

(What?)

FIFTY BUCKS AN OUNCE?! Nevermind.


Fifty bucks an ouch?
